Fixing the Tree View window [message #1841324]

For a given diagram, I need to show a tree structure of items that is always available when the user is working with the diagram. This is similar to the "Model Explorer", but the tree should only show some types of semantic elements (and not all files, different projects, etc.).

Is there a way to do this in Sirius?

I have experimented with a Tree diagram. I like the view that it presents. But the window is completely independent of the "source" diagram. It's also not so obvious for the user how to open this new window?

Can I for example associate a Tree diagram with another Diagram so that it always open as soon as the other diagram is opened?

Hello

There is no such ability in Sirius to synchronise two editors. You have to do it by yourself.
I would recommend to use a IPartListener to know when an editor is opened or closed [1]
Then you can test if the given IWorkbenchPart part is an instance of a org.eclipse.sirius.diagram.ui.tools.api.editor.DDiagramEditor. Then you can get information and call Sirius API [2] to open another representation (in your case the Tree representation)

[1] http://archive.eclipse.org/eclipse/downloads/documentation/2.0/html/plugins/org.eclipse.platform.doc.isv/reference/api/org/eclipse/ui/IPartService.html
[2] org.eclipse.sirius.ui.business.api.dialect.DialectUIServices.openEditor(Session, DRepresentation, IProgressMonitor)

Best regards

Thanks for this tip laurent.

A follow up question is how to "call Sirius API".

I am quite familiar with adding Java services to a Sirius model. But can't seem to work out the documentation to access and call Sirius APIs.
For example, where is this API defined? How can I call it?
